I am always amazed by how some people, which seems to be growing, have not a clue about reasonable separation of transmissions as a physical bandwidth requirement.

For example, operating on 40 meters and suddenly having a station move within one or two kilohertz, usually in my passband, and call CQ or relocate a qso booted off from some other frequency.

Using well adjusted sideband tranmitters, requires a clear three kilohertz separation either down stream or up stream, depending on USB, or LSB mode of transmission.

A station inside another's passband is not splattering nor am I if you move inside that boundary.

I have often thought with shoes dropping and lesser qualified operators, the final solution might be channels, similar to CB. Just dial in channel one LSB. Now with this comes a caveat that all operators on a band conform to LSB or USB. Most now do this by convention, however that choice might be engineered out of the next generation of dumbed down ham transceivers.

It might in fact conserve band space and prevent a lot of brush fires.

I might also say, no NET owns a frequency anymore than any two or more stations in QSO do. Read Part 97.

There is no requirement for 3 kHz separation, just like there is no requirement for 3 kHz of bandwidth in a SSB transmission. Many hams run a lot smaller bandwidth. You are just used to the greater dynamic range offered by the 3 kHz bandwidth.

Using 3kHz and 100w, you are putting out a slightly weaker signal than someone running 2.4kHz and the same 100w due to spreading that energy across a greater bandwidth. Many contesters use 2.4kHz or even as small as 1.8kHz to get their signal out just that much better. True, it isn't the best dynamic range, but it get's the job done and allows for more congestion on the bands.

That being said, there is no excuse for jumping into someone's passband and calling away, interrupting an ongoing QSO. That's just bad manners.

Dave, all good points. The solution which isn't going to happen, isn't greater operator competency. Its designing radios that can't be used in certain ways.We should realize in a lot of the world the power limits are more than 6 db (one s unit ) below ours.That would stop a lot of the tresspassing and interference.

I've always thought ham radio was a hobby someting to have as something to have fun with and not get all bent out of shape about. I guess if one doesnt like what he/she hears one can always just shut off the radio and walk away! I dont let the crap and bad ops stress me out.

Did you ever consider the fact that they may not know that you are one khz above or below them? Just because you can hear them doesn't mean they can hear you? But you already know that because you are a knowledgeable radio operator, right? I would bet that most of the time it is NOT intentional,.

I"M curious,would he also be complaining about the 30 meter band, ? it is the one with channels? I don't have a radio for it .HOW is that working out? yea, channnels is a great idea, worked for cb didn't it ? what planet are you on? My radio is almost 30 years old, and have to problem with slectivity if someone is operating ok , I also have a filter between my ears called a brain, and a good listener shouln't have a problem with some splatter, I am sure my ten watts splatters all over the band, get real ... I'll conceed some foreign stations can splatter a lot , but like they say, don't stress out, turn the dial, chill out , regroup or read e ham for a laugh . by the way, looked on the internet, they still sell geritol, take a swig and chill out ha ha . kg4ymc
